"It seems that all roads lead to the Postojna cave, rather than to Rome," said a satisfied Marjan Batagelj, CEO of the Postojna Cave Park. 7,781 people visited the Cave on Tuesday, while 3,522 people visited Predjama Castle.

Visitor numbers up in other karst caves as well
The number of visits to the Škocjan Cave Park is also increasing by the year, but management ensures that the pressure of visitors is not harmful to the cave. By 1st of August, the Cave had been visited by 116,000, with expected 190,000 by the end of the year. More than 50 guides are employed there and groups need to book their visits.

On average, foreign visitors by far make up the majority, the ratio is 80:20. Fortunately, the increase in visitor numbers is not harming the subterranean environment, says Borut Peric, expert of the Škocjan Cave Park.
